Suzy was walking through her local shopping mall when she began to feel intensely anxious. The anxiety was accompanied by sensations of choking, smothering, and a sudden sense that people and stores around her were unreal. She began to fear that she was going crazy, and the more she worried about this the more anxious she became. A guard, seeing that she was in distress, brought her to the mall office where she was able to lie down. A few minutes later the symptoms began to subside. She went home after leaving the mall but she did not tell her husband what had happened.
A week later she had a similar attack while she was walking down the street. She was able to reach her house where she lay down until the attack ended. In the following 3 weeks she had two more attacks. Between attacks she was constantly worried about having another attack. The patient was finally forced to tell her husband about the problem because she was so fearful of not being able to get help if an attack occurred that she would not leave her house alone or travel on public transportation.
